I just became a monthly patron of @fosstodon
If you like Mastodon and want to see it succeed and replace Twitter, you need to support your instance too.
By helping pay for the hosting and maintenance of your instance you will not only make sure it can keep running, but you also give the admins a reason to ensure that it's run and moderated to your liking.
If you're an instance admin, let people know how to support you.
Fosstodon is an English speaking Mastodon instance that is open to anyone who is interested in technology; particularly free & open source software.
